Oncologist is a physician who specializes in oncology, the branch of medicine that deals with cancer. An oncologist provides patient’s care throughout the course of the cancer disease. There are three main fields in which oncologists usually; radiotherapy, surgical and medical. Oncologists first diagnose a cancer using biopsy, endoscopy, X-ray, CT scanning, MRI, PET scanning, ultrasound or other radiological methods. Nuclear medicine, blood tests and tumor markers are also used for diagnosis. After establishing a diagnosis, oncologists discuss the disease type and stage of the cancer with the patient. Staging is very important as it helps dictate the type of cancer treatment patient will receive. Oncologist continues to oversee a patient’s care through treatment, helping the patient manage cancer-related pain and dealing with treatment side effects. After the initial therapy, the oncologist continues to follow the patient to detect a return of the cancer or confirm a cancer-free remission.
